Sold in bulk, we sell multiple varieties of knitted and non-woven wet wipes for wiping down equipment and machines inside of cleanrooms.

Cleanroom Standards. Before international cleanroom classifications and standards were adopted by the International Organization for Standards (ISO), the U.S. General Service Administration’s standards (known as 209E) were used by most manufacturers in most countries.

Federal Standard 209E classified clean rooms based on how many .5 micron particles could be counted in the room per cubic foot. If a clearness had 100 0.5 micron particles per cubic foot or less it was classified as a class 100 room. This standard divided cleanrooms as being in one of 6 classes: Class 1, Class 10, Class 100, Class 1000, Class 10000, and Class 100000.

What is a micron particle? One micron is one-hundredth the width of a human hair. The smallest particle seen with the naked eye is a 10 micron particle. Although cleanrooms are under positive pressure, micro-organisms can exist on clothing and unwashed hands, and keep in mind humans shed our outermost layer of skin every 24 hours: 1 billion flakes every 24 hours. One flake is 35 microns.
